RAILWAY-CAR GEAR.

SPECIFICATION forming part of Letters PatentNo. 449,643, dated March 31,1891.

Application tiled August '7, 1890.

To all whom it may concern:

Be it known that I, JOHN M. BLONDELL, a citizen of the United States,residing at Baltimore, and State of Maryland, have invented 5 certainnewand useful Improvements in Railway-Car Gear; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable thers skilled in the art to which itappertains to make and use the same.

My invention relates to what is known in the trade as railway-oar gear-*that is to say, that portion of the running-gear of astreet-railway-car vehicle comprising the axle j ourn al-box, thecarryin g-sprin gs, the pedestal .stay-brace, and the posts forsecuringthe axle to the body of the car; and my improvement consists of certainnovel parts and combination of parts, the separate features of whichwill be separately and specicall y pointed out inthe claims concludingthis specication, in connection with lthe accompanying drawings, inWhich- Figure l represents a side elevation of a railway-car gearembracing my invention. Fig. 2 is avertical longitudinal section of thesame. Fig. 3 is a vertical cross-section of the same, taken on the linea ce of Fig. 2. Fig. 4 is a horizontal section taken on the line b b ofFig. 2. Fig. 5 shows one of the separate guide-irons for the journal-boxguide-posts of the gear; and Fig. 6 shows the inside face of theaxle-box lid to expose its removable plate, which receives theend-thrust of the axle.

The object of my invention is to producea car-gear having separatewearing parts which are adapted for adjustment to present newwearing-surfaces at the wearing-points, to reverse their relativepositions to their wearing portions, and to remove and renew them whennecessary, and all this at very little cost in time, labor, andmaterial.

My invention gives the important advantage of removing the old gear asan entirety from the body of the car and of quickly replacing it by arepaired or new one, which advantage cannot be obtained in gearconstructed with posts running through the sill of the car. v

c shows a portion of the pedestal stay-brace,

-by bolts passing up through th Serial No.' 361,377. (No model.)

which is secured to the car-sill in the usual manner.

bis the pedestal, and b is the metal sillplate, which has a verticalflange b2 covering the outer face of the car-sill, and is secured eplate, and also by bolts through its flan ge. At its under side thisplate has screw-threaded bosses c, into which are screwed the posts d,the lower ends of which pass through the pedestal staybrace and aresecured thereto by nuts .e at the under side of said stay-brace.

f is the journal-box, which, with its pedestal, is supported upon thestay-brace and secured to the car by four posts.

g are the carrying-springs mounted upon the pedestal by the posts oneach side of the journal-box d, and 7L is a supplemental spring upon thejournal-box, of less height than the carrying-springs, to receive thegreatest load oi the car.

The vertical movement o f the car-bod y upon its springs causes theposts to move through the pedestal, and these posts, as I have provided,take the place of the usual pedestalrods, Which pass up through theearsill and permit the car-gear to be constructed as an entirety, withits posts independentof any connection with the car-body. As a means ofpreventing the wear of these pedestal-posts and the wear of the sides ofthe journal-box, I provide a removable wear part for each. For the boxguide-posts such wearing part is a cylindrical sleeve i, abutting uponand between the stay-brace and the sill-plate bosses, and for thejournal-box such wearing part is a separate guide-iron j, having aconcave Wear-face conforming to the convex surface of the guide-sleeve,as seen in Figs. 4 and 5. This guide-iron is preferably held in placeagainst the side of the journal-box by ribs k, so that it can be liftedout and a new one inserted. These guide-posts have heretofore been usedbearing directly upon the axle-box, and both the posts and the box wererendered useless by such wear. This guide-iron is also preferably madewedge-shaped, so as to be slipped down into its seatbetween thebox-ribs.

The pedestals are formed with seats l for the rubber cushions m, whichare 'provided roo with metal-sleeved seats n for the springs, while ametal cap o forms a seat for the upper cud ol the spring and a seat forthe upper rubber cushion p, which is placed against the underside ot'the sill-plate. To protect the posts of these springs from wear bycontact with the metal seats ot the springs, I provide the said postswith cylindrical sleeves q, which, like the guide-sleeves for thejournal-'box and post, abut upon and between the screw-th readed bossesof the sill-plate and the stay-brace. These wear-sleeves of all theposts can be turned or rotated to present a new wearingsurface, and theycan be turned end for end to change the location of the wearing-surface,and they can be readily and cheaply removed and replaced by new sleeveswhen desired, and thus avoid the expense and trouble of replacing theposts themselves. These sleeves form auxiliary posts and reenforce andstrengthen the posts proper, and these sleeves form additionalshoulder-bearings to these posts, and serve to strengthen, stiften, andkeep the gear in rm condition, and thereby lessen the rocking movementof the parts in the direction of the thrust of the car and theirconsequent loosening.

The axle-box lid 9' is provided with a removable bearing-plate s at itsinner side to receive the end-thrust of the axle t, and I make thisplate of brass or other suitable bean ing metal and seat it in the lidbyribs to permit its renewal when worn. I provide the stay-brace with anabutment u, against which that end of the gear abuts which is oppositeto the direction of the draft for the purpose of receiving andsustaining the thrust of the axle-box against the gear in line with thedraft, and thereby prevent the tilting and driving back of the gear.

\Vhile I prefer to use the removable wcai= plates at the sides of:thejournal-box, yet it is obvious that the guide-posts with renewablewear-sleeves may be used in direct wearcontact with the box. It is alsoobvious that the box wear-plates may be used with the posts without thewear-sleevcs- I claim as my improvementl. In combination, in arailway-car gear, the axle-box, the posts CZ, the sleeves i, the

pedestal-sill, stay-brace plates b a., and the carryin g-sprin gs, thesaid posts havin g screwthreaded shouldered ends supporting said platesand the said sleeves forming the guide and wear bearings for the box, asshown and described.

2. In a railway-car gear, the combination, with the axle-box and thepedestahof the box guide-posts, their wear-sleeves, and the wearplatesremovably secured to said box.

In a railway-car gear, the combination, with the axle-box and thepedestal, of the box guide-posts and the box removable wearplates.

4. In a railway-car gear, the combination, with the axle-box, thepedestal, and its posts, of the stay`brace having an abut-ment for thepedestal.

5. In a railway-car gear, the axle-box having its lid formed withdovetail guide-ribs on its inner side, in combination with abearingplate secured within said guide-ribs and the axle, as shown anddescribed.

In testimony whereof I alx mysignature in presence of two witnesses.
